Excellent, thank you.

But the gas is not supporting the piston until the piston is released. The piston froms a rigid wall of the cylinder until release. Have I missed something obvious?

Just a question that will hopefully improve my lack of understanding. A thought experiment. I have two cylinders both with frictionless pistons constrained to move in the z direction (against gravity) the same distance in both. So, the intial volume and final volume will be the same for both...
